Select the calibration option in the resistivity scan menu. Se-
lect the line on which you have attached the probes and select 
Calibration.  The  calibration  should  now  be  completed.  The 
data will be fixed as soil level. In automatic search or manual 
search  modes,  you  can  scan  with  the  obtained  calibration 
value. 

You will need to redo the calibration in each different scan or 
area.  

For deleting the calibration and returning to the interval of the 
device on manufacture, select the Reset option on the calibra-
tion menu. Therefore, the calibration values of the device will 
be reset to factory defaults.
